[@dhonors999]

Just want to chime in that pulsed lasers don't just exist because of electrical restrictions, they have many interesting properties, uses, and advantages compared to CW lasers. For example, in laser cutting, a sufficiently fast pulsed laser will dump energy into the material so quickly that the heat does not have time to dissipate before the material vaporizes, giving a much cleaner cut.

[@marca9955]

CW lasers don't also do that?

[@tylisirn]

@@marca9955 Lower peak output, so they heat up the material slower at the exact point of burn, or they have to be more powerful to achieve same output. They dump more energy into the material overall, but we don't want that, we want to burn exactly what we want to burn and touch nothing else. So the pulsed laser is more controlled, the CW is less, but allows faster cutting. There are pros and cons to each. Also depending on material, the pulsed laser also can allow the vaporized material to clear the cut before the laser dumps more heat into it, while the CW will dump some of the energy into the vapor cloud, resulting in absorption and scattering.

[@randfee]

while I understand what you're saying, technically, the guys' statement is correct. If you had a cw laser with the same average power as a pulsed laser's peak power, than you would achieve the same thing if you gated the cw laser accordingly (which might be impossible electrically for high loads if it's >xMHz). Anyways, a 1MHz 1ns pulsed laser with 1kW average power has 1MW peak power. If you use that to process at 1m/s than you could achieve similar results if you processed using a 1MW cw laser at 1000m/s , just get a fast polygon scanner :P - well, obviously I'm aware of the thermal limitations in optical components and also power-density limits during most material processes. If you want higher peak powers/fluences however, you're out of luck. Imagine a 100kHz 1ps laser with 200W average power - one can get those off-the shelf too. That's 2GW peak power. Now we need a small rocket to match the power output, or two standard sized nuclear power plants... Not gonna happen. --> Pulsed lasers will win! regards - a laser physicist.

[@jasonharrison25]

It also allows time for some of the smoke to clear out of the way so as to not block the laser. A CW laser has to shine through the smoke generated while a pulsed one can be timed to limit the smoke interaction thus imparting more energy into the target

[@BetaDude40]

The chemical storage was only a small factor for the decommissioning of the Boeing YAL-1. Testing showed that the atmosphere had too much of an affect on the powerful laser, causing it to lose a significant amount of energy due to heat and light scattering. While they initially billeted the laser as being able to operate from hundreds of kilometers away from its target, after testing it was shown the actual effective range was not nearly as long as they had hoped. They would basically have to fly into hostile airspace to get a chance to shoot their targets long enough to destroy them, which defeated the purpose of a standoff ABMS. As of yet, there is no effective way to destroy an ICBM during its first phase of the launch because they are extremely fast and positioned very far inland in most nations that have them. Most efforts nowadays are into stopping them during the second phase (the ~15 minutes while they are freefalling in space) or the third phase (the ~2 minutes of terminal velocity before airburst of the warhead). As of right now, the big huge chemical laser of the YAL-1 will probably remain unused, unless we decide to put those things in space, lol

[@PhilJonesIII]

[@Neo-vz8nh]

I don't think it would operate in space either. Every laser has a divergence, which is in a range of a few degrees. They are very focused from close but become huge beam at a distance. Even with lower then one degree divergance in few hunred km distance the laser beam would be still around a kilometer wide.

[@psychopiper8224]

@@Neo-vz8nh I have a feeling that if their testing concluded the atmosphere is the factor causing it to lose its effective range, I would trust their word and assume it would work fine in space.

Great video. One nerdy thing: The Death Star did use pulses. My brother and I had a longstanding argument about this because we're very mature people. The remaster shows it as clear as day - There's a targeting laser but pulses are what destroys Alderaan.

[@jamesphillips2285]

You can handwave that pulsed lasers are more effective because they give the material burned off the surface time to drift away. Otherwise the clouds of material can obscure the remaining undamaged surface.

[@FluidKaos]

High power continuous lasers suffer from a problem called 'blooming', where the energy in the laser beam ionizes the air and causes a spreading lensing effect that defocuses the energy of the laser at distance. It's part of the reason why most modern laser weapons are pulsed power and not continuous. They get their shots off so fast that the air doesn't have time to ionize before the energy has been put into the target.

[@BierBart12]

​@@jamesphillips2285 Probably also helps when each pulse targets a different part of the planet, causing an explosive chain reaction in the crust

[@Turboy65]

The Death Star primary weapon is not a laser though it does use lasers for aiming. It is a directed energy weapon that uses a form of beam energy that suppresses the nuclear Strong Force, causing atoms to fly apart with the same energy release as thermonuclear fusion reactions. ALL the matter the beam contacts reacts in this manner., which explains the destructive consequences of even a light strike.

This is the most amazing chemical reaction you’ve ever shown on this channel. Holy s***!!!!! It’s scary to think what a one megawatt laser could do when just a couple watt laser with a small focus lights things on fire from across the room 😅 Also small correction: ultra high power electric laser diodes I believe are usually pulsed to maximize the average power output with the diode’s duty cycle capability in mind. Delivering thousands of watts continuously isn’t an issue. By pulsing the incoming signal, the diode can emit a higher average power level than if it was running continuous duty, and the peaks will be hotter upon contact with the material the laser is cutting optimizing the performance even more. There are actually laser diodes that pump out thousands of watts continuous duty now (mostly infrared ones in the 1100nm range). Backyard scientist had a 2kW cleaning laser on his channel and that thing is literally a deadly weapon 😅

The reason all the pilots for the F35 were getting sick was because the Onboard Oxygen Generating System (OBOGS) was operating too hot. The OBOGS draws from the engines, and instead of pulling oxygen out of the atmosphere, it was cracking the oxygen molecules into singlet oxygen. It ate the filters, and the pilots ended up breathing the filter material, along with singlet oxygen, doing serious damage to their lungs. They had to re-engineer the entire OBOGS system to make it run cooler.

Hmmm it's funny. @3:44 that electron configuration violates Hund's rule of maximum multiplicity. I never realised it was possible. I always thought excited electrons were forced to obey BOTH Pauli and Hund. Thank you for the update.

[@kylebowles9820]

Hund's rule comes from a statistical gradient whereas Pauli is more of a law that has to do with spin

[@AeroGraphica]

What would be the power of the reactions you showed us, and how the light is converted into a beam ?

[@neutronenstern.]

A laser works by exciting a medium like a gas or a crystal with "normal" light or high voltage,or heat. Then to the left and to the right of this medium there will be a mirrow. One of them is semitransparent. So i think this light coming from the reaction is used to excite the medium. Then when this medium is excited some atoms in it will de-excite by coincidence and release a photon. This photon then bounces back and forth between the mirrow, and by this hits other atoms in the medium, which then get de-exited by this photon, and thus release another photon with same frequency and same polarisation and same phase. So then two photons bounce back and forth, then four, then eight, ... . Then due to the fact that one mirrow is semitransparent, with some probability a photon will pass. These passing photons then make up the laser beam, which is very directional, coherent (same phase) and polarized and with high intensity.

[@kmoecub]

@@neutronenstern. The light created by the chemical reaction is the laser. It's not used to excite anything. It gets collected by mirrors and passed through lenses to direct it onto the target.

[@CraftyF0X]

@@kmoecub Great, now I wonder why it emits 2 diff wavelenght 762nm and 634nm and if this count as "monochromatic" when technically it emits in 2 different frequency ?

[@meloney]

@@CraftyF0X Monochrome also means that it (could be) is a value of one colour as well, so depending on the definition you use, it could mean that as well :)

[@u1zha]

​@@kmoecub LASER means Light Amplification by Stimulated Emission of Radiation. I think you should stop and reread the encyclopedia section about lasers. If you don't leverage excited states then emission is probably not gonna deserve to be called stimulated but just spontaneous. The benefit of excited medium and stimulated emission is that the light is coherent, the exciting beam and the emitted beam go parallel at the get-go. The method with mirrors and lenses does not allow creating a straight beam of the laser kind, from a spontaneously emitted light (that travels in all the random directions). Try it. There was an Action Lab video about it too.

1:20 The death star laser is also pulsed, but charge over minutes and fire over seconds, not pulsing on the order of milliseconds.

[@kmoecub]

It's not pulsed. That would be like saying that naval artillary is a fully automatic weapon, but it takes minutes to chamber the projectile instead of miliseconds.

[@u1zha]

@@kmoecub How long a laser fire is no longer pulsed in your opinion? Is there a rule? 😃

[@labrat810]

The only way the 'laser' on the Death Star could have had such destructive force (in-universe, or otherwise), would be if it was 'pulsed' in quantum wavelengths; functioning as a 'disruptor' more than a 'laser', basically. Disruptors exist in-universe, and even 'laser guns' in Star Wars are not a laser beam weapon, they're a laser-excited 'packetized' energy-projectile DEW.

Some constructive criticism: Your not using a proper gas mask (It doesn't cover your entire face, also the filters and mask look like a Particle filter, are you sure this is a GAS mask?) and aren't using a fume hood or doing the experiment outside. Chlorine gas is toxic and extremely toxic corrosive towards almost anything, aka: you, your pets, your walls, the water- and power line in your walls, your eyes. This was extremely bad practice, even with your warning notification, as such a notification does not protect yourself and it also understates what a terrible idea it is to produce large amounts of chlorine gas in an enclosed room with no proper PPE. Please don’t take this comment the wrong way, the video was really interesting, I just want to offer some constructive criticism. Please stay safe :)

@@bhc1892 Fr lmfao. First of all that looks like a multi gas cartridge, not a particulate filter (just because you see a mesh doesn't mean it's particulate, multi gas cartridges have the same pattern, e.g. 6006, and also in the first place organic vapor cartridges are magenta/purple) and he's posted pictures of his setup on Instagram before and it looks just fine.

That is not, in fact, possible. I wish it was but it isn't. The stuff is so angry that it will react with anything, including itself, to stabilize, either by oxidizing something around it, or by oxidizing other singlet oxygen to create O2 the stuff we breath.

At the beginning of the video I thought the red light was a video effect of some sort. What an interesting video!

[@Dr_Mario2007]

Chemical lasers are equally as interesting since they tend to be chemically venomous by themselves separately, yet when you combine the substances together, they react violently, to the point they give up a lot of light that can then be selectively amplified. It's just attractive to the military because it means they don't have to drag the nuclear power plant across the road (considering the fact that diesel fuel is a precious commodity nowadays, especially with the price - it all adds up quickly). Yet for shorter laser wavelength, electric lasers are best for that because of energy required to obtain UV and X-ray laser, while chemical lasers are much more efficient in the Infrared and red bands.

[@MirlitronOne]

Chemically venomous?

[@Dr_Mario2007]

@@MirlitronOne It's more of a figure of speech, some chemicals involved in generation of laser light are just as dangerous - like the Halogens in general, in this case Chlorine.

The laser that was first used to measure the distance to the moon and how that varies, travel 240,000 miles (on average) was only 14,000 Watts. It didn't cut through anything because of the short duration of the pulse.

[@paradoxfromks]

The YAL-1 with its several hundred kilometers range, still was within the missile defense envelope of the launcher and completely vulnerable to interception. I talked to a chemist involved in the program and was told that an accidental explosion of the fully loaded craft would have been "spectacular", and i got the impression as in maybe nuclear bomb "spectacular". The YAL-1 was retired because the corrosion from carrying (not leaking) the chemicals had completely compromised the aircraft's structure.

This is a great video, but I'm a little disappointed in your sponsor this week. You're an ambassador for critical thinking and the scientific process, making content that is well researched and founded. Snake-oil beauty products that have no medical or scientific backing feels a little....not right. I'm glad you're getting sponsors, I think you totally deserve it, you make awesome content, but I hate to see you hawking something over-priced beauty crap that "gives you chiseled skin."

[@kmoecub]

I'm not advoating for snake-oil, but did you read any of the studies he cited? Did you take a moment to consider that the product may actually do what it claims to do, at least to some degree? I'm not critical of your stance (in fact I agree with it), but to comment without checking things out is as bad as selling snake oil IMO.

@@kmoecub I have seen way too many beauty products in my lifetime to take any of this nonsense seriously. If somebody that actually figured out something that made you look younger, it would be literally everywhere. We're talking electrode belts and laser masks here... They all have "scientific studies" that support them, and yet they always die off in oblivion because they don't actually work.
